Very eye catching, completely unique ring, hand formed out of bronze, adorned with green zirconia and a little bit of green patina. Full of dynamic, interesting shapes and lines. Diameter of this ring is 16.7 mm, so it's European size 13 (with a little plus) or US size 6 1/4. Please, make sure that the diameter of the ring in milimeters is right for you because there are many different size conversion charts out there. If you have any questions, please ask.
